DH Instruments MOLSTIC-S SUPPLY ONLY PLATFORM 1-4 IN. AND 1-2 IN Installation Sheet

The 1/4 in. and 1/2 in. supply only molstic-S platforms,
P/N 401876 and 401877, provide inlet gas pressure
regulation to either the Device Under Test (DUT) or the
downstream molstic-S mounting systems. They are
used to control the pressure supplied to an upstream
DUT, or to adjust the flow rate through the system
while calibrating a downstream DUT.
High pressure gases are potentially hazardous.
Energy stored in these gases can be released
unexpectedly and with extreme force.
pressure systems should be assembled and
operated only by personnel who have been
instructed in proper safety practices.

OPERATION OF SUPPLY ONLY MOLSTIC-S
Set regulator outlet pressure to minimum.
Rotate the knob of the pressure reducing regulator
in the counterclockwise direction until the spring
force of the diaphragm is relieved. Insure that the
shut-off valve is in the closed position.
Connect the gas supply.
Connect the gas supply to the quick connect stem
(either 1/4 in. or 1/2 in. tube). The gas supply
pressure should not exceed 1.7 MPa (250 psig).
Insert the stem into the quick connect body.
Connect the outlet of the supply only platform to
either the DUT or the inlet of the molstic-S.

connecting the quick connect stem to the
quick connect body (located on the inlet side
of the regulator).
